17 Claims.

This invention relates to typographical composing machines of the kind known commercially under the registered trade-mark Linotype, wherein circulating matrices are released from a channelled magazine in the order in which their characters are to appear in print and then assembled into line, the composed line transferred to the face of a slotted mould, the mould filled with molten metal to form a type bar or slug against the matrices which produce the type characters thereon, and the matrices thereafter elevated and returned through the medium of distributing mechanism to the channels in the magazine from which they started. More particularly, it relates to machines equipped with a plurality of magazines which may contain different matrix fonts, the magazines beingadjustable columnwise to bring a selected magazine into operative position with respect to assembling and distributing mechanism.

To effect such columnwise adjustment of the magazines a manually operated lever connected through lever and link mechanism, or any similar mechanism, to a shift frame supporting the magazines, has been provided. Power-operated mechan sm for effecting the columnwise adjustment of the magazines has been proposed, but such mechanism has comprised either means for bringing successive magazines into operative position or a reversible power drive operable independently of the machine drive.

According to the present invent on, a typographical composing machine comprises a column of magazines which is adjustable to allow a selected magazine to be brought into operative position, a power drive operated by the machine drive or by an independent continuously rotatable drive for shifting said column of magazines and pro-selecting means for causing said power drive to bring any selected magazine of the column into operative position. There may be included means for connecting said power drive to the machine drive, and the pre-selecting means may be operative to disconnect the power drive upon the arrival of the selected magazine in operative position.

In carrying out the invention, the typographical composing machine comprises a column of magazines mounted on a bracket which is adjustable in opposite directions to bring a selected magazine into operative position, a power drive for moving said bracket in both directions, a device mounted on the bracket so as to be operable to disconnect the power drive, a number of adjustable members corresponding to the number of magazines in the column and mounted on a fixed part of the machine, and means for moving any selected one of said members into the path of the device so as to operate the device and disconnect the power drive upon the arrival of the selected magazine in. operative position. The adjustable members may be pivotally supported and a cam may be adjustable to pro-determined positions to rock a pre-selected member into the path of the disconnect ng device.

A further feature of the invention consists in a typographical composing machine comprising a column of magazines which is adjustable to bring a selected magazine into operative position, a magazine locator member which is rotatable during adjustment of the magazines, 2, locator arm which is arranged to be engageable with said member at positions corresponding to the adjusted positions of the magazines, means for moving said arm out of engagement with the rotatable member to free the magazine column for adjustment, and means for moving the arm into engagement with the member at another position to hold the magazine column in adjusted position. Preferably the rotatable locator member comprising a pulley connected to a weight for counterbalancing the weight of the magazines and the locator arm is pivotally mounted on a' fixed part of the machine adjacent said pulley. The locator arm may be so arranged that movement thereof out of engagement with the locator member actuates mechanism for connecting the magazine column. to a power drive for shifting said column and movement of the locator arm into engagement with the locator member disconnects the power drive.

The invention will now be described by way of example with reference to the accompanying drawings in which:

' Figure 1 is a side elevation of a portion of a typographical composing machine showing the power-operated mechanism for effecting columnwise adjustment of magazine according to the present invention;

Figure 2 is a rear sectional View taken on the line II--II of Figure 1;

Figure 3 is a side elevation of the control device for bringing the power-operated mechanism into operation;

Figure 4 is a rear view partly broken away and showing the magazine pro-selector mechanism;

Figure 6 is a part plan view of the clutch control for the power-operated mechanism;

Figure 7 is a side elevation of a portion of a typographical composing machine showing an alternative form of mechanism for effecting a raising and lowering movement of the magazine column; and

Figure 8 is a rear sectional view taken on the line VIII-VIII of Figure 7.

Referring to Figure 1 of the drawings, a column of four magazines 4 (two only of which are shown) is arranged in an inclined position in a machine frame 2, and each magazine I is removably mounted on a base frame carried by a bracket or shift frame 3 which is movable in the machine frame 2 so as to bring any selected magazine or magazines of the column into operative position in relation to matrix assembling and distributing mechanisms (not shown). To counterbalance the weight of the bracket 3' and magazines I, the bracket 3 is formed with a downward extension i which is slidable in a guide frame secured to the machine frame. Qne end of a chain 5 is secured to the extension t and the other end of the chain is passed around and secured to a pulley 7, so tending to turn the pulley in a clockwise direction. The pulley l is provided with a hub 83 which is mounted on a shaft 9 carried by the machine frame and the hub 8 is integral with a pulley It having a larger diameter than the pulley i. A second chain I l is passed around and secured at one end to the pulley lo, the chain i I being passed over a jockey pulley i2 and secured at the other end to a counter-balancing weight It which thus tends to turn the pulley in a counter-clockwise direction, in the manner set forth in the specification of Patent No. 2,605,888, dated August 5, 1952.

After the bracket 3 has been moved to bring a selected magazine into operative position in relation to the assembling and distributing mechanisms, the selected magazine is, according to the present invention, maintained and located in correct operative position by means of a recessed locator arm Hi (see Figure 3) which is brought into en agement with one of the locator studs L -L projecting from the side of the pulley it. The number of locator studs (L -L on the pulley corresponds to the number of magazines in the column, and each locator stud is so arranged on the pulley that on rotation thereof the locator stud corresponding to the selected magazine is brought into correct position for engagement by the locator arm M. The locator arm is pivotally mounted at It on the guide frame 5 and is provided with an extension 95 connected by means of a flexible cable it to a hand-operated lever ll for rendering power-operated mechanism active to bring a pro-selected magazine into operative position, as will now be more fully explained.

As is well known, the machine is provided with a power driven and constantly revolving intermediate shaft l8 (see Figures 1 to 3) from which certain organs of the machine are driven. In the present arrangement the driving portion I9 01 a friction clutch is keyed to the intermediate shaft i8 so as to be rotatable therewith but movable axially therealong into and out of engagement with a driven portion 29 of the clutch which is freely mounted on the intermediate shaft It. If preferred, the clutch i9, 26, may be mounted on an independent continuously rotatable shaft. The driven portion 28 of the clutch is integral with a worm 21 having a hub 22 which is freely mounted on the intermediate shaft i8 and supported in bearings 23, 24, forming part of a bracket 25 fixed to the machine frame. The worm 2| meshes with a worm wheel 25 secured to a shaft 27 mounted in bearings 2 3, 29, in bracket 25, to which shaft El a profile cam is secured. The profile cam 3t is engaged a roller 3! mounted on a stud 32 on a cam lever 33 which is pivoted at 35.- to the bracket The cam lever 33 is adjustably connected by a link 35 to an arm 36 secured to a shaft 3? to which shaft is secured an arm 38 connected by a link 39 to the downward extension 4 of the bracket 3 on which the magazines are mounted. Thus, when the driving portion is of the friction clutch is brought into engagement with the driven portion the profile cam 39 is rotated to raise or lower the column of magazines.

Operation of the clutch i8, 23, is effected by a lever 48 (see Figure 6) pivotally mounted at ii in the machine frame and having at one end a fork 48 engaging a groove i'i formed in the driving portion It of the clutch. An arm ii,- secured to the lever is is connected to one end of a spring 4% which is secured at its other end to the machine frame, so as to pull the driving portion 19 of the clutch into engagement with the driven portion 253. An extension arm 25 pivotally connected to the lever is connected to a toggle arm 4% which is pivotally connected at 4? to the other toggle arm it pivoted at it to the machine frame. A link 29 is connected at one end to the pivot ii and atits other end to the extension 55 of the locator arm i (see Figure 3), the arrangement being such that movement of the locator arm i-i operates the toggle arms iii, it to effect engagement or disengagement of the clutch i9, 29. The locator arm I4 is held in engagement with a locator stud (L or L or L or L by means of a spring and is disengaged from a stud against the action of spring 59 by operation of the hand lever ii. The locator arm It is held in such disengaged position by the engagement of a catch 52 thereon with a latch 52 and the clutch 55, 2c, is held in engaged position (and hence the magazine column is moved) until the latch 52 is released by the magazine pro-selector mechanism now to be described.

Thelatch 52 is pivotally mounted at 53 (see Figure 4) on the guide frame 5, and rests on a stop peg Ell. The latch 52 is provided with a setting screw 55 which is arranged to be engaged by the top end of a parallel motion bar 55% mounted on arms 5? pivoted at 53 to the guide frame 5. Movement of the parallel motion bar 56 is effected by the rocking of a triangularshaped tumbler 59 carrying three rollers 53 and freely mounted on a stud 5i fixed to the extension 4 of the magazine supporting bracket Mounted on the guide frame 5 and disposed between the upper and lower ends thereof are four interponents 62 (corresponding to the number of magazines in use) and any selected one of such interponents can be moved into the path of the tumbler 59 so as to rock the tumbler when the extension t (and hence the column or" magazines) reaches a pre-selected position.

Each interponent -2 is freely suspended on a stud 53 secured to the guide frame 5 and is held out of the path of the tumbler 58 by a spring 6 s secured at one end to the interponent and at the other end to the guide frame 5. Each interponent 62 is provided with a roller -5 which is held by its spring 64 against a slidable cam 01' selector bar 66 provided with four raised surfaces 8? (corresponding to the number of interpcnents 62).

Such surfaces 61 are so disposed on the bar that movement of the selector bar 65 to Dre selected positions causes one of the raised surfaces fi't to engage a roller 55 on an interponent $2 and so move the selected internment into the path of the tumbler 58s The selector bar 66 is formed with a rack; 61* which is engaged by a spur pinion 68 secured to the end of a rotatable shaft 6.9. mounted in the guide frame 5. The other end of the shaft 69 has secured thereto a bevel gear with which meshes a bevel gear H (see Figure 3) secured to one end of a rotatable shaft '12 mounted. in bearings on the machine frame. The shaft 52 is, provided at its other end with a pre-selector contro handle l3 (see also Figure 5) having a springpressed detent is for engaging notches '15, a graduated dial it on the machine frame.

To select a required magazine to be brought into operative position, the pro-selector control handle "it is moved to the appropriate position on the dial it thereby moving the selector bar 66 to bring an interponent $2 into the path of the tumbler 5E; The hand lever i! is then operated to disengage the locator arm is from a looator stud (L or L or L or L the locator arm id being held in disengaged position by the latch 52. The movement of the locator arm it engages the friction clutch (I9, 26) (as hereinbefore explained) so causing the downward extension t of the magazine supporting bracket 3 to be moved to a position in which the tumbler 59 thereon is rocked by the pro-selected interponent 62 so as to press against the parallel motion bar 56 and lift the end thereof into engagement with the screw 55. The consequent disengagement of the latch 52 from the catch 5| allows the spring 55 to move the locator arm Ml, so disengaging the clutch !9, 2e, and bringing the looator arm into engagement with another locator stud appropriate to the selected magazine.

In the modified construction shown in Figures 7 and 8, the profile cam 39 is replaced by a spiral gear 17 mounted on the shaft 2'5. The spiral gear l"! meshes with a spiral gear l8 mounted on a shaft 19 supported in bearings 89, 8!, on the machine frame. A chain wheel 82 is loosely mounted on the shaft 19 and is connected by a chain 83 to a chain wheel 84 secured to, the pulley H A gear wheel 85 is loosely mounted on the shaft 19 and meshes with a gear wheel 86 mounted on a short shaft 81 and secured to a chain wheel 88 which is connected by a chain 89 to a chain wheel 99 secured to the pulley It.

A dog clutch M is slidably mounted on keys on the shaft 79 so as to be engageable on the one hand with teeth on the chain wheel 82 or to be engageable on the other hand with teeth on the gear wheel 85. Thus, if the clutch i9, '20, is engaged and the shaft Til is driven in a counts"- clockwise direction as viewed in Figure '7, the clutch 9|, when engaged with the chain wheel 82, will rotate the pulley If! in counter-clockwise direction and the magazine column will be lifted. If, however, the clutch 9! is engaged with the gear wheel 85 the gear wheel 86 and pulley ill are driven in a clockwise direction so that the magazine column is lowered. Movement of the clutch 9 l' is effected by a forked lever 92 engaging a groove formed on the clutch 9|, the lever 92 being mounted on a shaft 93' to which is connected an arm 94 provided with a roller 95 which engages between projections 96 on a slidahle bar 91 mounted in guides on the machine frame. The slidable bar 9'! is provided at its lower end with. a spring-loaded plunger St and at its uppe end with a sprin -loaded lunger $3, which pioneers ar e eaeeebl by a fin r 100 mm r-udins from the lower end of; the. extension 4.

When the extension 4 reaches the limi f its downward movement the f nger um engages the plunger 93 and moves the slidable bar 91 to the position shown in F ures '7 and 8 in which the clutch 9; is engaged with the chain wheel 82 and the extension 4 and column of magazines can be lifted by the power-operated mechanism. When the extension 4 reaches the limit of its upward movement the fin er 100 engages the plunger 99 and moves the slidable bar 9'! to a positi n in which the clutch 9! is n a d with th eear wheel'flfi and he extension 4 an m s zine column can e low ed.
